LFO 1 - Shape & Amount
This screen controls the waveshape and amount of Low Frequency Oscillator 1.
The LFO can be used to produce vibrato (when routed to pitch), or tremolo
(when routed to volume). The LFO can be routed to control any of the Realtime
Modulation destinations (page 123). The five LFO waveshapes are: Triangle,
Sine, Square, Sawtooth, and Random. The amount can be varied from -128 to
+127. Negative values will produce inverted waveshapes.
LFO 1 - Rate, Delay & Variation
This screen controls the rate, delay and variation of LFO 1.
LFO Rate
Varies the LFO speed from 0.052 Hz to 25 Hz (000-127).
LFO Delay
Sets the amount of time between hitting a key and the onset of modula-
tion. This can be used to simulate an effect often used by acoustic instru-
ment players, where the vibrato is brought in only after the initial note
pitch has been established. The delay range is variable from 0 to 13 sec-
onds (000-127).
LFO Variation
Sets the amount of random variation of an LFO each time a key is pressed.
This function is useful for ensemble effects, where each note played has a
slightly different modulation rate. The higher the number, the greater the
note to note variation in LFO rate. LFO variation is variable from 000-127.
